medial ligament of ankle joint

[TA]
compound ligament consisting of four component ligaments that pass downward from the medial malleolus of the tibia to the tarsal bones: 1) tibionavicular ligament (pars tibionavicularis [NA]), 2) tibiocalcaneal ligament (pars tibiocalcanea [NA]), 3) anterior tibiotalar ligament (pars tibiotalaris anterior [NA]), and 4) posterior tibiotalar ligament (pars tibiotalaris posterior [NA]).

Compound ligament consisting of four component ligaments that pass downward from the medial malleolus of the tibia to the tarsal bones: 1) tibionavicular ligament (pars tibionavicularis [TA]), 2) tibiocalcaneal ligament (pars tibiocalcanea [TA]), 3) anterior tibiotalar ligament (pars tibiotalaris anterior), and 4) posterior tibiotalar ligament (pars tibiotalaris posterior).
Synonym(s): ligamentum deltoideum.

deltoid ligament

The strong triangular ligament, on the inner side of the ankle, which helps to bind the foot to the leg. A torn deltoid ligament may leave an unstable ankle that ‘goes over’ easily.

Evaluation of the integrity of the deltoid ligament in supination external rotation ankle fractures: A systematic review of the literature.
Their conclusions stated that bimalleolar ORIF provided far superior results than closed treatment of ankle fractures, and that patients with a medial malleolar fracture (as opposed to just a deltoid ligament rupture) faired significantly worse when treated by closed reduction.
Baird and Jackson (12) studied a series of 24 SE4 and PE3 and four equivalents, where disruption of the deltoid ligament was diagnosed clinically by medial tenderness over the ligament and by radiographic confirmation of a widened mortise.
In both cases, an effort was made to repair the deltoid ligament. Lindenbaum (13) reports a follow-up of 3 years showing no evidence of arthritis, range of motion 5[degrees] less than the contralateral side and stability under a lateral stress radiograph.
Excision of the lateral malleolus articular surface did not reduce rotational stability but division of the deltoid ligament caused a two-fold increase in rotational instability.
However, once the deltoid ligament was sectioned, all ankles showed a significant decrease in tibio-talar contact area.
There is no displacement on the AP view, since the deep portion of the deltoid ligament is not disrupted.
When the medial malleolus fragment was more than 2.8 cm wide (supracollicular fracture), the deltoid ligament was intact and the stress view was negative.
Repair of deltoid ligament ruptures offer no benefit when not associated with a medial malleolus fracture.
The disruption of the deltoid ligament rarely needs to be surgically addressed.
CONCLUSION: Deltoid ligament avulsion with medial malleolus fracture is very rare.
The repair of a ruptured deltoid ligament is not necessary in ankle fractures.
